Figure 3From: Channel estimation in OFDM systems operating under high mobility using Wiener filter combined basis expansion modelThe relationship between the coefficients of Wiener filter with orders 3 and that of Wiener filter with orders 2. In this figure we let σ2 → 0, p0 = 1, p1 = 4 and p = 2. The dashed lines represents the coefficients of Wiener filter with orders 2.Back to article page
